Well Im toying around that idea also just because I have a few turbos laying on a shelf hx35 hx 40 and a precision 66mm. Thought about bi turbo, but if I went turbo I'm leaning towards single. I'm just really up in the air about this one. I kind of wanted to keep her a bit tamed, but I love having fin on the street. It might be fun to do some roll racing out here since everyone likes to do the roll racing. My duster is built to go from a dig. I'm just weighing my options right now, I can get an SC motor pretty cheap, or I can use what I have and pull a bit more power. only problem I have at that point, What should I do trans wise, build the stock 4t65e or find an hd and build that. GM cars is a new territory to me, I'm just figuring all this stuff out.
